IW4052B
ANALOG MULTIPLEXER DEMULTIPLEXER
High-Performance Silicon-Gate CMOS
The IW4052B analog multiplexer/demultiplexer is digitally
controlled analog switches having low ON impedance and very
low OFF leakage current. Control of analog signals up to 20V
peak-to-peak can be achieved by digital signal amplitudes of 4.5
to 20V (if VCC - GND = 3V, a VCC - VEE of up to 13 V can be
controlled; for VCC - VEE level differences above 13V a VCC - GND
of at least 4.5V is required).
These multiplexer circuits dissipate extremely low quiescent
power over the full VCC -GND and VCC - VEE supply-voltage
ranges, independent of the logic state of the control signals.
When a logic “1”is present at the ENABLE input terminal all
ORDERING INFORMATION
channels are off.
IW4052BN Plastic
The IW4052 is a differential 4-channel multiplexer having two
IW4052BDW SOIC
binary control inputs. A and B, and an enable input. The two
TA = -55° to 125° C for all
binary input signals select 1 of 4 pairs of channels to turned on
packages
and connect the analog inputs to the outputs.
• Operating Voltage Range: 3.0 to 18 V
• Maximum input current of 1 µA at 18 V over full package-temperature range; 100 nA at 18 V
and 25°C
• Noise margin (over full package temperature range):
1.0 V min @ 5.0 V supply
2.0 V min @ 10.0 V supply
2.5 V min @ 15.0 V supply

In certain applications, the external load-resistor current may include both VCC and signal-line
components.
This device contains protection circuitry to guard against damage due to high static
voltages or electric fields. However, precautions must be taken to avoid applications of any voltage
higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and
VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC.
Unused digital pins must be tied to an appropriate logic voltage level (e.g., either GND or
VCC). Unused Analog I/O pins may be left open or terminated.
